Default veteran but "new"

All right guys here we go. I have raced off road for about three years and got out of it due to havin a family. My son and I are gettin back into it. He has the new Slash 4X4, and I have a custom built T4/B4 dirt oval latemodel. I am currently running the old Novak SS 5800 8.5T motor and SC system. Well, needless to say when we went to the track for the first time in 6 years, i was BLOWN away!!!!! All the new tech is mind blowing to say the least. Ok, aside from all the new tech, it was all pretty understanding. I started noticing all these new "rectangled shaped" battery packs. So, me bein a curious natured person, i started askin. I got the deer in the head lights look. FROM EVERYONE. like where in the heck have you been. Well the answer came from a very helpful friend of mine that I bought the slash from. Its LiPo man. the latest and greatest. Then he started this whole techno savy jargen that sounded like a greek instructor in a class full of fluent students. So heres my question. With my current motor speedo set up, what do I need to go fast, "safely" with out burnin my car up or my house. any help would be greatly appreciated.

As far as I'm aware what you have is one of the earliest brushless systems. the 5800 was designed as a mild modified. Have a look at what the lowest turn motor your ESC manual says it will handle, then find a modern motor of that turn, that should help you go fast as cheaply as possible.

To go to LiPo batteries you will need a low Voltage cut-off, without it you will damage the LiPos when the dump. The newest ESCs have this feature built in. So maybe think about a new ESC as well.

I'd been out of the sport for a few years until recently too. I came back racing 12th only because it was the only class I could compete in with old gear, and then only really at club level. I'm only just updating everything now, and finding I pretty much have to do it all at once. Do you realise 12th scale cars don't even have T-bars anymore!?
